No metallicity effect for low mass <strong>planets</strong><br />

Mayor et al. 2011<br />

•HARPS high precision sample: [Fe/H] for giant gaseous <strong>planets</strong> (black), for <strong>planets</strong> less<br />

massive than 30 ME (red), and for the global combined sample stars (blue).<br />

•No metallicity effect for low mass <strong>planets</strong>.<br />

•Even absence of low mass <strong>planets</strong> at high [Fe/H]?<br />

•Natural outcome in the core accretion formation model.<br />
